MotorsQuestion 222 of 1506

Why does a switched reluctance motor need precise electronic control?

  1. It has no winding in its stator
  2. Torque is nonlinear against current
  3. It runs from a single phase only
  4. It needs a mechanical speed governor
Show answer

Correct answer: Torque is nonlinear against current

The torque does not follow current in a simple way, so phase switching must be exact.
